Age is an important feature at the time of early breast cancer diagnosis. Radiotherapy is a mandatory component of treatment for breast-conserving strategies in early disease stages. Breast radiotherapy has rapidly evolved in the last 20 years.

Age and risk for local recurrence guide the decision-making process to electro-optimal treatment. Radiotherapy technological versatility offers multiple options for individualized (risk-age adapted) recommendations.
